Premium laptop power adapter replacement factory right now? It’s always important to look for the main model number rather than the ‘range’ listed around the keyboard as this isn’t always enough detail to find the right charger for your device. If you can’t locate the sticker or it’s difficult to read, you could take a look at the original invoice/receipt or check the manual that came with your laptop. If the laptop hasn’t discharged completely, you can also find the model number on the powered on machine. Discover extra info at laptop adapter replacement.

Watts is calculated by multiplying the Volts by the Amps. Therefore a 19V charger with an Amps rating of 3.42A would be a 65W charger 19V x 3.42A = 65W. The higher the Amps the higher the Watts, provided the Voltage remains constant. It’s a Maximum Rating. The Amps and Watts rating on a laptop charger is a maximum output rating. This means that the charger is capable of outputting up to the maximum Watts rating. ie it can push up to x Amps of water through the pipe at a force of up to x Watts at the pressure (Volts) provided by the charger. However, to avoid any damage to your laptop it’s usually a good idea to check the polarity against that of the laptop or your original charger.

Once you’ve found a charger that provides the correct amount of power, the next step is to determine your polarity. For barrel-style plugs, you’ll see a symbol with a “+” and “-“ sign, connected to a ring and a dot. The symbol connected to the outer ring represents the polarity of the outside of the barrel. Similarly, the sign connected to the dot represents the polarity of the inside of the barrel. Most devices use an adapter with the positive connector on the center, but there are exceptions.

There are no guarantees on quality. Many of the universal chargers we looked at on eBay and Amazon came with no mention at all on warranty either. By nature of a universal charger, many of its parts are removable (such as the pin section). These can be wobbly or poorly fitting and will degrade over time. Finally, many universal laptop chargers have a switch to manually select the required voltage. Plugging the charger into your laptop with the wrong voltage selected can cause irreversible damage to your laptop. In summary for universal laptop power adaptors, we can’t recommend them as there are too many factors that can risk causing damage to your laptop.
